Process of making hydrochloric acid and calcium carbid.



UNITED STATES PATENT OFFICE.

a WILLIAM H. SEAMON, OF EL PASO, TEXAS. PROCESS OF MAKING HYDROCHLORIC ACID AND CALCIUM CARBID- Specification of Letters Patent.

Patented July 24, 1906.

processes in treating fused calcium chlorid with acetylene gas therewith, Wherebg and calcium carbi or other gases mixed hydrochloric-acid gas may be produced, and

' the advantages derived com rise the utilization of calcium chlorid, whic is now a waste product in chemical industries and produced in enormous quantities and which by my improved processes is made a valuable product, as by the utilization of pure acetylene gas or hydrocarbon gases mixed therewith I am able not only to manufacture the hydrochloricacid gas bya cheaper process than with processes now employed and also produce a calcium carbid economically.

In carrying out the steps of my process calcium chlorid is brought to a fused state in any suitable furnace in which coal, wood, gaseous fuel, or-even electricity may be employed for such purpose, after which acetylene as, either pure or mixed with other gases whic are rich in hydrocarbon, is introduced under a moderate pressure through a pipe into the fused mass of calcium chlorid, after which the following v and hydrochloric acid whic reaction takes place-'i. e. CaC 2I-IOl. he hydrochloric acid passes off from the fused mass in agaseous state and is condensed by water, as now the practice in the present methods of making hydrochloric acid. The calcium carbid remains in the furnace and may be removed when the reaction is ended, after which a new supply of calcium chlorid may be added.

From the foregoing it will be noted that an improvedmethod is afl'orded for economically manufacturing hydrochloric-acid gas and also calcium carbid from calcium chlorid from what is at present a Waste product and which is produced in large quantities.

What I claim is 1. The process of makin calcium carbid consists in fusmg ca cium chlorid and passing gaseous hydrocarbons through the fused mass, converting the calcium chlorid to calcium carbid, and collecting the hydrochloric acid thus produced, as set forth.

2. The process of making calcium carbid and hydrochloric acid Whichconsists in fusing calcium chlorid and passing acetylene through the fused mass, convertin the calcium chlorid to calcium carbid, and collecting the hydrochloric acid thus produced, as set forth In testimonywhereof I hereunto affix my signature in the presence of two witnesses.
